Instructions For Use:

Magnetic pins require a break-in period to de-iron the pins and temper their blunt edges before use.  Be sure to run them through several 5-10 minute cycles using a polishing compound like Otto Frei OF 610 Magnetic Tumbler solution or #750 Powered Shot Cleaner before mixing with other pins or using to finish your metals.  The break in period helps leach out residual iron from the pins that can effect successful brightening. The pins are ready for use when they no longer turn the water solution black.
